To alltuhom it concern: I

Be it known that I, Cnanmes W. Karena,

a citizen of the United States, residing at Newark, in the county ofEssex and State of New Jersey, have invented certain new and useful Imrovements in Acetylene-Gas Containers, 0 which the following is aspecification. 4

. This invention relates to the preparation of acet lene gas containersso that they can be safe y shipped and handled in the use of the gas,and more particularly the invention relates to the filling substancewith which the cylinder orv other receptacle is packed to divide itschamber into minute spaces or interstices to be occupied by the gas andacetone or other solvent of the gas.

The objects of the invention are to secure 8. I I I 'l in as in pgef c'us ension or perfectly sub-divided condition; thus secure completesafety; to obtain a filler which can be easily put into the cylinder orother receptacle and which completely fills the same; to secure adurable filler, which will not deteriorate in handling the containers;to secure an inexpensive filler; and to obtain other advantages andresults as may be brought out in t e following description.

In carrying out my invention, I mix laster of aris with a large excessof wa er, or exa e a out seven parts of water to SIX parts of plaster ofparis. This makes a i%uid of about the consistency of cream, or w ichcan be readilyvpoured. cylinder or other receptacle with the liquid,preferably by pouring it through the valve opening of the c linder, andet 1t set or harden. After e mixture has set sufliwa r in it is driven 0is left a filhn who as Y roughu,,itsel-f-innnmera In other words, it v'ke a s but the holes are very minute and evenly distributed; in fact,the said spaces or interstices are It is'an important point of myimproved .filler that while it is rigid enough to maintain its shapeagainst sagging. either before I then fill the RQGSDDJIlter- V toominute to be seen withthe naked eye. Such a filler readily receives orafter being wet with the acetone or other solvent of the gas andagainstall-jars and shocks of the containers as a whole, it is at the same timeimpressible so that it can be dented at its outer surface withoutaffecting the rest of the filler. In other words, a blow upon the fillerwill only cause an indentation without cracking or fracturing the filleras a Whole, and such indentation closely fits the instrument which hasbeen driven into the filler or with which the blow Examiw .was given.The-result of this in practice is that a blow or impact upon the outsideof the cylinder suflicient to dent it simply dents the filler inside thecylinder correspondingly and does not crack, crumble or fracture thefiller otherwise. In other words, the effect of the blow or impact isrestricted to the place which is hit or indented and not transmitted tothe .rest of the filler, 'or the filler is non-frangible by the samemeans-to'which it is impressible.

Furthermore, my im roved filler because of its fine uniformly istributedspaces or interstices holds the solvent of the gas in suspension veryeffectively and reduces its loss by being blown out of the containerwith the escaping gas, since the gas releases itself slowly from myimproved filler.

The surplus water may be driven oifby heating, by passing warm airthrough the cylinder containing the set filler, or any other meanscommonly employed for similar pur oses', or any combinatlon of two ormore of t ese means. I have found that simply heating to about 180degrees Fahrenheit will produce satisfactory results.

The plaster of paris may be used alone, or there may be mixed with itany other substances, such as infusorial earth, magnesia, charcoal,asbes as, W vicestone, and so orth, w W] vary its we or a sorbentproperties. I also use the term plaster of pans to include what is knownas Keene cement or gypsum burned or calcined with alum, calcium sulfate,and other plasters which are simply slight variations of plaster ofparis and will produce the same'characteristics in a filler as thoseabove described.

The advantages of my filler are that it is molded in the cylinder orother receptacle and therefore completely fills the same; that it can bepoured into the cylinder through the usual valve opening,

and thereforeafter l filler; that t e filler readily the cylinder hasbeen finished and tested; that the distribution of the minute spacesthroughout the filler is even, uniform and unchangeable; that the filleris rigid'enough 5 to maintain its shape against sagging, jars,

shocks, and the like and yet is at the same time impressible so that thecylinder or other receptacle can be dented at its outside withoutafiectin the safety qualities of the absorbs the solvent and gas andretains 1t; that it is perfectly safe, and that it is cheap.

A filler of my improved composition can of course be molded or castmdependent 1.5 of a cylinder or other receptacle and after such shapes wdrying be placed in the same and packed with asbestos or othersubstances, as in common. In such a case the filler could be molded inone Ipiece or in several pieces, and

ich are well-known. I refer, however, to mold or cast the fillerdirectly in the cylinder or other receptacle as above set forth, so thatit forms an integral core completely filling the cylinder and in '25intimate contact therewith at all points of its inner surface. In any.event, the filler must be a solid or imperforate mass, that is, withoutborings or holes of any kind except the minute spaces or cells invisibleto the 80 naked eye which are formed naturally, and

if it is composed of several pieces put in one cylinder there must be nospaces or openings left between or around them. Y

By the term acetylene gas I mean to include any gas having simllarexplosive properties whether in a normal condition, or compressed, orliquefied, or dissolved in a li 'u1d, or the like. Having thus describedthe invention, what I claim is 1. A filler for acetylene gas containers,containing plaster of paris set in an impressible non-frangible form.

2. In an acetylene gas container, the combination with a receptacle, ofa filler in said ller in said chamber in an imperforate filling teriorcham er, of an integral imperforate core filling t e said chamber andcontaining plaster of paris set in an impressible non-.

frangible form.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES W. KAISER.
